Abstract
The invention relates to a method in image processing, wherein an image in digital form is in coding phase compressed, quantized by a quantization matrix (QL, QC) and coded by a coding matrix (HL, HK, HL), wherein one or more data frames are formed. In a decoding phase decoding, dequantization and decompression is carried out to the information comprised in the data frame.
